Sometimes when I enter a town, I find TONS of stuff laying on the ground; meat, guns, resources, etc... It's like someone killed 10 zombies and never bothered to pick up the drops. This is just more crap for the server to keep track of until it gets picked up.
How about adding a Wandering Scavenger to the world that wanders from town to town as well as out into the boonies and stops to pick up any dropped items that are within a certain radius of him. When confronted by a player, he'll run rather than fight and will be just slightly faster than a player, but slows momentarily after taking damage. When killed, his pack will be full; mostly with the recent stuff that he's picked up but also with a few higher end items such as an axe and/or ammo. This will make him a desirable target for players and it could be fun trying to hunt him down.
He'd be identifiable by a larger backpack, or maybe use the current backpack, but have a buncha items half hanging out of it to indicate that it's overloaded with goodies. Maybe he could be hunched over from the weight of it all. :D
